I Confessed What Happened with My Brother’s Girlfriend
I’m going to tell you something about my younger brother, and I’m not doing it to judge him, because the truth is I’m just as slutty as he is. We grew up in a house where sex was never a forbidden topic, and I guess that’s why we both turned out the way we did. I’m two years older than him, so when I was little I watched him grow into a man, and when I got older I had to hear things no brother should ever tell his sister.
Lucas’s sex life was always intense. Since he started university, he never stopped. His first serious girlfriend, whom I’m going to call Vale, practically lived in his room. I’d come home from school and hear them through the wall, with zero attempt at being quiet, as if the house belonged to them. At first it embarrassed me; later I stopped caring. You get used to it, and I even confess I ended up paying attention. Vale’s moans stuck to me: that “harder, harder” she’d cry when he was really fucking her well, the wet sound of skin slapping skin, and every now and then a “like that, like that, shove your whole cock in me” that made me squeeze my thighs together in bed. Many nights I ended up with my hand between my legs, biting my lips, coming to the rhythm my brother set while he pounded his girlfriend.
His real initiation, though, wasn’t with Vale. It was with the daughter of the woman our father was dating at the time. I’ll call her Ana. One night she stayed over at our house, Dad had arranged everything with her mother, and I had just moved in with my first boyfriend, a week before turning eighteen. That night Lucas stopped being a virgin with her. He told me later, with that puppyish pride he never lost, and in graphic detail: how she sat on top of him, grabbed his cock with both hands, spit on it slowly and worked it little by little into her cunt until he felt like he was dying; how she rode him face down, pressing her tits against his chest, whispering for him to come inside; and how he came, the first time in his life inside a woman, feeling the load rise from his balls to the tip and pour out into Ana’s hot cunt while she laughed with her mouth pressed to his neck.

The detail that changed everything in my head I discovered almost by accident. One day, while tidying the bathroom, I found a pair of my used panties where they shouldn’t have been, outside the laundry basket, hidden behind a towel. It took me a while to understand it and, when I did, I didn’t know whether to laugh or cover my face. My brother liked smelling them. Not mine for any special reason, just whichever ones he had on hand. They were stiff, with the clear mark where he’d come on them, and the elastic still smelled like saliva.
Over the years that taste became a full ritual. His girlfriend at the time, Romina, far from being horrified, played along like nobody else. She got him other people’s clothes, thongs she took from other women’s laundry, sometimes from her own cousins, from an aunt, from sisters-in-law. She didn’t just hand them to him: she herself brought them up to his nose while they were in bed, feeding that obsession with a patience that, when I found out, left me breathless.
And I found out because he told me. One night he came home half drunk and pretty upset after a party. He sat on the edge of my bed to vent, said things were weird with Romina and he didn’t know whether to keep going. I, practical as always, brushed it off: he was young, he was handsome, he’d never lack women. But he shook his head and told me the truth.
—It’s not that easy to leave her —he said, looking at his hands—. She makes me feel things nobody else ever has.
That’s when I decided to really listen. To get him to keep opening up, I had to open up too, and I told him about my own experiences, about nights with my friend Belén, about how we ate each other’s cunts until dawn, about how Belén would finger me with three fingers and eat me at the same time until I screamed. It worked. Lucas let his guard down and started telling me about the intimacy he had with Romina, my sister-in-law, that woman who from day one had awakened a curiosity in me I never quite admitted.

What he described was a twisted game and, I confess, a brilliant one. In the middle of sex, with his cock buried deep in Romina’s cunt, she would pull out from some nearby hiding place an item of intimate clothing belonging to someone else. She’d slowly bring it up to his face, and just seeing it appear would make him lose his mind. They’d pass it back and forth, smell it, kiss over it, their tongues meeting through the damp fabric soaked with another woman’s scent. He’d keep fucking her meanwhile, on all fours, grabbing her by the hair, driving into her to the balls with every thrust.
What finished driving him wild came at the end. Just before he came, Romina would whisper in his ear whose item it was. And almost always it was from someone in the family, someone close, someone he knew and saw at Sunday lunches. That instant, of knowing, was what made him explode. He told me how he pulled out of her cunt at the last second, how Romina turned over and opened her mouth, and how he emptied semen onto her tongue while she rubbed her tits with the thong from the cousin or the aunt. He told me in a level of detail he didn’t need to give me, and I listened with my breathing getting shorter and shorter, my legs clamped together under the quilt.
—And sometimes —he added, almost in a whisper— she’d wrap it around my cock and make me come with it on. She’d wrap me up like a glove, work me through the fabric with her hand, and I’d end up filling her with cum while she said in my ear, “This one’s your cousin’s, look at it well.”
I wasn’t prepared for that line. I got hot in a way that made me ashamed, I felt my cunt soak my underwear all at once. You shouldn’t be feeling this, not with him, not because of this. But I felt it anyway, and I felt something else too: the certainty that somewhere in those fantasies I was there, that at some point my own panties had gone through his nose and his cock, and that Romina was bisexual, something I had suspected all along.

The years passed. They got back together, split up, got back together again, until it all ended abruptly. Romina found him with another woman inside the same house they shared. A stupid, shameless betrayal, in his own bed. And it was exactly in that time, with the relationship dying, that what I never told anyone happened.
Lucas was away on a trip, down south. Romina showed up at the house one afternoon, wrecked, sensing what she already knew. I saw how broken she was and didn’t want to leave her alone. We cooked something, put on a series, and I suggested we finish watching it in my room, more comfortable, away from the living room. I told myself it was to comfort her. The truth is I’d spent years imagining exactly that situation, imagining my sister-in-law’s cunt, imagining what the mouth of the woman my brother fucked every night would taste like.
We lay side by side, dressed, watching the screen. At some point I felt her arm slowly cross over my stomach, shyly, as if testing the waters. I didn’t move it away. The night went on, dawn crept in, and around three I realized she had fallen asleep pressed against me, her hand still on my stomach.
I turned off the TV and left only the little lamp in the corner on. I was about to fall asleep when her hand moved, barely, but with intent. Two fingers slid down to the waistband of my pants and stayed there, waiting. I knew immediately what she wanted. I turned toward her, held her, settled my face a hand’s breadth from hers.
—You’re very beautiful —I told her.
—Thanks, Caro —she replied.
And she said nothing else. She found my mouth and kissed me with an urgency I hadn’t expected, a long, wet kiss, the kind that erases any excuse. I felt her tongue forcing its way in, her hand rising from my stomach to my nape, and any thought of stopping dissolved right there.

We started slowly, kissing each other’s necks, behind the ear, in that area where perfume mixes with the real smell of skin. And Romina smelled like a woman on fire, like a wet cunt under clothes, like something beyond any fragrance, a warm scent that got into my head and lit me up all over. We stayed like that for a long while, in no hurry, until curiosity got the better of me and I broke the silence.
—What do you like about my brother? —I asked against her mouth.
—That he’s big —she answered, her voice broken by her breathing—. And that he never gets tired. He fucks me for hours and doesn’t come until I ask him to.
I laughed softly and kissed her again, and thinking of him, of my brother’s cock going in and out of the woman in my bed, of how many times I’d heard them from the other side of the wall, turned me on in a way that’s hard to explain. I yanked her T-shirt off. She had medium-sized breasts, round, with pink nipples and pale areolas drawn with such precision it made me want to bite them. And I did bite them, gently at first and then with hunger, sucked them whole, covered them in saliva while she grabbed my head and asked for more, pressing my face against her tits.
We undressed slowly and without shame. She was fuller than I was, with soft curves, a round ass, and a patch of dark trimmed hair over her cunt; I was leaner, firmer, my nipples hard from being turned on for so long. We touched first with our hands, getting to know each other, and talked very little because we both knew what we were there for. My fingers slid down her belly to the hair, and I slipped slowly between her lips and found her sex soaked, dripping; she did the same, opened my legs and sank two fingers into my cunt in one move, drawing a moan from me that got trapped in her mouth.
We fingered ourselves at the same time, forehead to forehead, watching each other do it. I drove three fingers into her to the knuckles and with my thumb pressed on her swollen clit; she did the same to me, with that skill you learn when you know exactly where to go. She let out a “like that, slut, like that” that was exactly what she would have said to my brother, and that made me close my eyes and bite her shoulder. I felt her cunt clench around my fingers, the juice running down my hand, and when she moaned long and low I knew she’d already come once.
Then she turned over and we settled one over the other, in sixty-nine, her mouth on my cunt and mine on hers. I pried her lips open with my thumbs and saw her pink, shiny, open cunt, and I dove in without thinking. I licked her from bottom to top, slowly, savoring that woman taste I’d wanted to try for years. I sucked her clit between my lips, tugged it gently with my teeth, pushed my tongue inside as far as I could. She did the same to me, with a hot, precise tongue that knew where to press; she slid it in and out of me, dragged the tip over my clit with calculated slowness, until I couldn’t take it anymore and begged her not to stop.
While I licked her I couldn’t stop thinking that this was the same cunt my brother ate, the same lips that opened for his cock, the same legs I heard opening so many nights on the other side of the wall. Imagining him in my place, buried in her face, licking the same clit I now had in my mouth, sent me spiraling all at once. I felt her respond, felt her drive two fingers into my cunt while she sucked my clit hard, and I came in her mouth with a long spasm, crushing her head between my thighs, while I drank everything that came out of her cunt without being able to breathe.
She came a minute later, arched, stifling her cry against my thigh, soaking my face. I felt her tremble all over, shake, and I didn’t let go until she stopped moving. We stayed like that for a while, panting, the smell of both of us in our noses. We ended up holding each other, sweaty, without saying a word, and fell asleep like that, tangled together, as if none of it needed explaining.
***
Lucas never found out. He would only know if he ever read this someday. A couple of months later, his relationship with Romina ended for good, and with it all the fantasies I’d built in my head came crashing down one by one. I had imagined ways for the three of us to end up in the same bed, him fucking us in turns, she and I sharing his cock in our mouths, and suddenly there was no her anymore.
But he remained. And so did my suspicions. Now, older, putting the pieces together from that season he spent down south after the breakup, I’m almost certain my brother slept with one of our aunts, an old maid who lives there and has always had a reputation for being hornier than anyone. He spent weeks at her house, the two of them alone, and I know Lucas too well to believe he didn’t bury his cock in her to the hilt every night.
My next goal is to get that confession out of him. I want him to tell me everything, every detail, like he always does. And if it turns out to be true, if he really fucked our aunt, I’ve already made a decision: the next one to go through my brother’s bed, with his cock inside me, will be me.
